Abstract

Purpose: This study investigates the impact of integrating Kudus local culture within the PMRI (Indonesian Realistic Mathematics Education) framework to enhance students' numeracy literacy and engagement. Method: A quasi-experimental design with a posttest-only control group was implemented in a public junior high school in Kudus, Indonesia. Two seventh-grade classes were randomly selected; the experimental group received PMRI-based instruction enriched with local cultural values, while the control group followed conventional teaching. Data analysis involved normality and homogeneity tests, followed by an independent samples t-test. Findings: Results showed a significant difference between the two groups (t = 2.926, p < 0.05), with the experimental group demonstrating higher numeracy literacy, motivation, and stronger contextual understanding. Significance: The integration of local culture through the PMRI approach bridges abstract mathematical concepts with real-world experience, fostering both conceptual mastery and cultural appreciation. This approach offers a promising model for advancing mathematics education in diverse cultural settings.

Abstract

Kesulitan yang sering dihadapi mahasiswa Program Studi Pendidikan Matematika di Universitas Borneo Tarakan berakar dari pemahaman dasar matematika yang lemah, mencakup konsep prasyarat seperti aljabar, kalkulus dasar, dan logika matematika. Kondisi ini menghambat mereka dalam mempelajari materi perkuliahan yang lebih kompleks, berpotensi memicu ketertinggalan akademis, dan menurunkan motivasi belajar. Untuk mengatasi masalah krusial ini, diusulkan program intervensi sistematis dan terstruktur bernama Klinik Matematika dengan pendekatan matrikulasi intensif. Tujuan utama kegiatan ini adalah memperkuat kemampuan dasar matematika mahasiswa baru serta angkatan sebelumnya, sekaligus memotivasi mereka agar memiliki semangat dan kesiapan optimal untuk mengikuti perkuliahan. Kegiatan ini dilaksanakan di kampus Universitas Borneo Tarakan, menyasar 56 mahasiswa baru Program Studi Pendidikan Matematika Angkatan 2025. Metode yang digunakan adalah pembelajaran interaktif yang berpusat pada mahasiswa, meliputi penyampaian materi ringkas, latihan soal, diskusi, dan pendekatan klinik di mana dosen memberikan bantuan personal untuk mengatasi miskonsepsi spesifik. Evaluasi menggunakan tes kemampuan dasar (pretes dan posttes) menunjukkan kenaikan rata-rata nilai yang signifikan. Kesimpulannya, program Klinik Matematika ini berhasil dan sangat efektif dalam mengoptimalkan kompetensi dasar matematika mahasiswa, menjadikannya solusi yang direkomendasikan untuk menjadi agenda rutin tahunan.

Abstract

Understanding algebraic concepts is an important prerequisite for advanced mathematics learning because it involves a transition from symbolic manipulation to structural thinking and proof. This study analyzes students’ understanding of algebraic concepts in a Linear Algebra course using the APOS (Action, Process, Object, Schema) theoretical framework. The method is descriptive qualitative, with systematic application of APOS indicators in the domain of Linear Algebra. Data were collected through conceptual tests and analysis of proof and problem-solving tasks. Data analysis involved reduction and categorization based on APOS development. The results showed three patterns of understanding: (1) students in the low-ability category failed to meet the criteria for the Action, Process, Object, and Schema stages; (2) the medium category showed partial comprehension—reaching the Process stage and parts of the Object stage on routine problems but failing at the Action stage for abstract constructive problems; and (3) the high category generally reached the Schema stage on constructive problems but showed failure at the Action stage on problems requiring proofs of basic axioms, or vice versa. The findings suggest emphasizing development of the Action stage and the process–object linkages to strengthen transfer to the Schema. Practical recommendations include gradual constructive tasks, mediated proof-of-concept learning, and APOS-indicator-based formative assessment.
